xxxxERICSSON Application Research Problems After initial beta, the GemXplore Case was very usable. –we succeeded! Operator support required: Not an open market –card needs to be programmed by operator Only Comviq did support SIM data download on the SMSC Lack of documentation of GemXPlore Case –8 bit SMS is also treated as data download –Many parameters are only documented in standards –high priority for display necessary in certain cases Use of prototype phones –interaction between SIM card and mobile equipment

xxxxERICSSON Application Research Problems No debug tools, all testing is done on the phone –long edit/compiler/debug cycle –lack of simulator –disassembler for PDUs Script language is extremely limited –hard to use syntax –lack of instructions (swap arrived too late in the update) –no variables Suspect card to miss ESMS processing when phone is busy Instruction set SIM card and security info is kept secret –we reversed engineered it partly at great cost of time

xxxxERICSSON Application Research Future Limited application area for SIM Application Toolkit in the future after 3-5 years: –WAP –IP connectivity Very convenient today for accessing many different services Operators need to make it more open to make it useful for third party developers Cell identifier is a very interesting possibility for location based services
